[00:00:00]Dive down to the ocean's darkest depths and crouch [music] low in the world's tiniest gardens.

[00:00:07]This adventure is a double journey to the extremes of our planet.

[00:00:12]In the deep, sunless sea, creatures create their own glowing light in a magical dance called bioluminescence.

[00:00:19]Meet the googly-eyed barreleye fish with its see-through head, the elusive giant squid, lobsters are marine crustaceans with hard shells, long antennae, and strong claws, and they live on the ocean floor hiding among rocks.

[00:00:40]Lobsters have two very different claws.

[00:00:43]One is a big crusher claw for breaking shells, and the other is a sharper pincer for cutting and tearing.

[00:01:05]Orcas are easily recognizable with their striking black and white coloration, which helps with camouflage when hunting.

[00:01:12]Orcas have complex brains and exhibit behaviors like teaching, learning, cooperation, and problem-solving.

[00:01:19]Orcas in marine parks have shown signs of stress and shortened lifespans. The Blackfish documentary brought widespread attention to this issue.

[00:01:44]Honeybees live in colonies with a complex [music] social structure including a queen, worker bees, and drones. Honeybees perform a dance to communicate the location of flowers, water, or new nest sites. Honeybees are responsible for pollinating around 1/3 of the food we eat, including fruits, vegetables, and nuts.

[00:02:20]Crabs are arthropods, related to lobsters, shrimp, and even insects. They have hard exoskeletons, shells, made of chitin. Crabs have five pairs of legs, with the front pair modified into claws, chelae, used for [music] defense and feeding.

[00:02:39]Crabs have complex behaviors, including problem-solving, communication, and using tools. Some decorate their shells for camouflage. Humans and even other crabs.

[00:03:06]Sawfish are rays, not sharks. They belong to the same group as stingrays and skates, elasmobranchs, [music] and have flattened bodies with gills on the underside.

[00:03:17]Sawfish are found in shallow coastal waters, estuaries, rivers, and mangrove swamps. Some species can even survive in freshwater. Sawfish mature late and produce few offspring, which makes it difficult for populations to recover.

[00:03:33]Sawfish are rays, not sharks. They belong [music] to the same group as stingrays and skates.

[00:03:54]>> Dolphins are warm-blooded mammals.

[00:03:57]They breathe air through a blowhole and nurse their young with milk.

[00:04:01]Dolphins have large, complex brains relative to their body size. They exhibit advanced problem-solving, self-awareness, and social behaviors, allowing them to keep swimming and watch for predators.

[00:04:29]Clownfish are known for their vibrant orange bodies with white bands outlined in black, though they can also be yellow, red, or even black depending on the species.

[00:04:40]Clownfish live in warm waters of the Indian and Pacific Oceans, including the Great Barrier Reef and Red Sea.

[00:05:03]Alligators can grow up to 11-15 ft (3.4-4.6 m) and weigh over 1,000 lb >> [music] >> (450 kg).

[00:05:15]Their bite force is around 2,000 (1,125 psi), strong enough to crush bones.

[00:05:21]Alligators are ectothermic (cold-blooded) and rely on the sun to regulate body temperature. In cold weather, they enter brumation, a hibernation-like state.

[00:05:32]Alligators have existed for over 37 >> Adult walruses can weigh up to 1.5 tons, 3,000 lb, >> [music] >> and grow over 11 ft, 3.3 m.

[00:06:00]Long males are much larger than females.

[00:06:03]Walruses have sensitive whiskers, vibrissae, up to 700 of them, used to detect food on the ocean floor.

[00:06:12]Walruses primarily eat benthic invertebrates, especially clams, snails, worms, Mantis's are ambush predators. They wait patiently and then attack with lightning speed. Their front legs are lined with sharp spikes to [music] grab and hold prey securely. Mantis's are the only insects that can turn their heads side to side, about 180°. This helps them track moving prey and stay alert for danger. Leaf cutter ants. Mantis's are ambush predators. They wait patiently and then attack with lightning speed.

[00:07:10]Whale is the largest animal to have ever lived on Earth.

[00:07:14]It can grow up to 100 ft, 30 m, long and weigh over 200 tons. Whales are known for their complex vocalizations.

[00:07:25]Humpback whales sing long patterned songs that can last [music] for hours.

[00:07:30]Whales can communicate over vast distances. Low frequency sounds can travel hundreds of miles underwater, especially species like sperm whales and orcas.

[00:07:56]>> Snakes are reptiles. They belong to the order Squamata and are closely related to lizards.

[00:08:03]Snakes can consume prey much larger than their heads because their jaws are connected by very stretchy ligaments.

[00:08:09]Snakes live in forests.

[00:08:26]Starfish don't have a brain or blood.

[00:08:30]Instead, they use a water vascular system to circulate nutrients and move.

[00:08:36]Starfish move using hundreds to thousands of tiny tube feet.

[00:08:56]Hammerhead sharks have a wide flattened head called a cephalofoil, which looks like a hammer hence the name.

[00:09:03]Hammerhead sharks have a wide flattened head called a cephalofoil, which looks like a hammer hence the name.

[00:09:10]Hammerhead species, like the scalloped and great hammerhead, are listed as endangered due to overfishing and finning. Hammerhead sharks have a wide flattened head called a cephalofoil, which looks like a hammer hence the name.

[00:09:26]Hammerhead sharks have a wide flattened head called a cephalofoil.

[00:09:43]>> Spiders play a crucial role in controlling insect populations, making them important for ecological balance.

[00:09:50]Spiders inject digestive enzymes into their prey and suck up the liquefied insides.

[00:09:56]Most spiders are solitary and predatory, feeding mainly on insects.

[00:10:01]Spiders produce different types of silk for different purposes. Webs, egg sacks, wrapping prey, etc. Whale sharks feed mainly on plankton, small fish, and krill, which they filter from the water using their wide mouths.

[00:10:31]Whale sharks have a distinctive pattern of white spots [music] and stripes. On a dark background, each pattern is unique, like a fingerprint. Whale sharks are found in warm tropical oceans around the world, usually near the surface or mid-depths. Whale sharks are listed as endangered by the IUCN due to threats from fishing, bycatch, and boat collisions.

[00:11:09]Mantas are not fish in the bony sense, like tuna or salmon.

[00:11:13]They are cartilaginous fish, related to sharks, skates, and other rays.

[00:11:18]Their skeletons are made entirely of cartilage.

[00:11:22]The giant oceanic manta ray is the largest ray in the world.

[00:11:26]Their wingspan can reach a colossal 7 m, 23 ft, or more, and they can [music] weigh up to 2,000 kg, 4,400 lb. They are cartilaginous fish, related to sharks, skates, and other rays.

[00:11:53]Place more mysterious than outer space.

[00:11:56]Now, shrink yourself down to discover the incredible surprises of the insect world right under your feet.

[00:12:02]Watch a caterpillar transform into a brilliant butterfly. See how ants build underground cities, and learn how beetles wear suits of shiny armor.

[00:12:11]Did you know some bugs can walk on water, carry objects 50 times their weight, or even look like beautiful flowers or scary sticks?
